8 Lower Belly Fat Workout Moves You Can Do At Home

Tasha Boyd13.08.2026

Let me say the quiet part loud before we get into anything else: you cannot spot-reduce fat off your lower abs, and I've never once told a client at the rec center that a crunch would melt it there specifically. What you CAN do is build real strength in the deep core muscles that sit under that area, and that strength shows up as better posture, less low-back nagging, and abs that actually engage when you need them to. These eight moves are the ones I've cued in class more times than I can count, each with a way in for a beginner and a way up for someone who's ready for more.

Reverse Crunch

This is the move I hand to almost every new lower-ab client because it isolates the lower rectus abdominis without your neck doing the work your hip flexors should be doing. Lie on your back, knees bent, and curl your hips up off the mat toward your ribs, using your hands flat on the floor for a little stability — exactly what you see here.

Supported version: keep your feet resting on the floor and just tilt your pelvis up a small amount — tiny range, big control.
Standard version: lift knees to a 90-degree angle and curl hips fully off the mat, pausing at the top.
Harder version: extend your legs straight up toward the ceiling before curling — more lever, more load.

The cue that actually fixes this move: your lower back should stay gently pressed into the floor the whole time. If it arches, you've gone too big too fast — shrink the range, not the effort.

Flutter Kicks

Flutter kicks build the endurance side of your lower abs — the part that keeps them switched on during a long walk or a day of carrying groceries, not just a single hard rep. Lie back, hands tucked under your lower back or hips for support, and alternate small, quick leg kicks a few inches off the floor.

The trick nobody tells you: this move gets harder the lower your legs go, not the higher. Beginners tend to kick way up near vertical thinking that's the challenge — it's actually the easy version.

Start with legs higher and knees slightly bent if your lower back is talking to you.
Progress by lowering your legs closer to the floor while keeping your low back flat.
Advance further by extending the set from 20 seconds up toward 45.

If you feel this move mostly in your hip flexors and not your abs, that's normal early on — keep the range small and let your core catch up before you chase depth.

Mountain Climbers

Cardio meets core

Mountain climbers earn their spot on this list because they combine core bracing with your heart rate going up — which matters, since general fat loss (not spot reduction) comes down to overall activity and calorie balance, and that's genuinely a question for a registered dietitian if you want it dialed in precisely. What I can tell you is how to do the move well.

Supported: stay in a plank and step one foot forward at a time slowly, no jump.
Standard: drive knees toward your chest at a controlled jog pace, keeping hips level — the position shown here.
Harder: pick up speed while keeping your hips from rocking side to side, which is where most people lose form.

I've coached this move about four thousand times, and the tell is always the hips — the second they start swinging like a pendulum, the core has checked out and the hip flexors took over.

Bicycle Twist Crunch

This one shows up in nearly every lower-ab study for a reason — it recruits the obliques alongside your rectus abdominis, which matters because your midsection works as a full unit, not isolated squares. Lie on your side of the body, hands behind your head, and extend one leg while curling the opposite elbow toward the bent knee, then switch.

Supported version: keep the extended leg resting near the floor instead of hovering.
Standard version: hold the extended leg a few inches up, as pictured, and slow the tempo down.
Harder version: add a full alternating cycle without letting either foot touch down between reps.

Slow this move down before you speed it up. A fast, sloppy bicycle crunch mostly just moves your elbows — a slow one with a real pause at the twist is where the obliques actually fire.

V-Up Hollow Hold

This is an advanced move, and I want to say that plainly rather than dress it up — it asks a lot of your lower back and hip flexors, so it's not where a beginner should start. Lying flat, you lift both legs and both arms up simultaneously into a V, reaching hands toward toes, keeping your low back pressed to the mat the entire time.

Build toward it with reverse crunches and flutter kicks for a few weeks first.
Start with a bent-knee version — knees bent, hands reaching toward shins instead of toes.
Progress to the full straight-leg V shown here once your lower back stays flat without effort.
Add a hold at the top for 2-3 seconds once the movement itself feels easy.

If your lower back lifts off the floor or you feel pinching rather than working, that's your body telling you to regress — not a signal to push through it.

Forearm Plank

The plank doesn't get enough credit as a lower-ab move because it's not flashy, but it teaches your deep core to brace under load — which is exactly what protects your lower back during literally everything else on this list. Forearms and toes on the floor, body in one long line, ribs pulled down rather than flared open.

Supported version: drop to your knees, keeping the same straight line from knees to shoulders.
Standard version: full plank on toes, forearms down, held for 20-30 seconds — what's pictured here.
Harder version: lift one foot a few inches off the floor at a time without letting your hips rotate.

My honest disclosure on this one: my dog Biscuit treats every plank I do on the garage floor as an invitation to walk directly under me, and holding form through that has taught me more about bracing than any cue I've ever given a class.

Straight-Leg Lower

This is one of the more underrated lower-ab moves because it isolates the exact muscles that keep your pelvis stable when your legs move — lying on your back, legs extended and lifted, one hand supporting behind you as you slowly lower and raise your legs together.

Beginner-friendly cue: keep both knees softly bent, which shortens the lever and takes real pressure off your lower back.
Standard version: legs straight, lowering only to where your low back stays flat — not to the floor.
Progression: lower legs closer to the ground and slow the tempo to a four-count down.

I'll route this one straight to scope: if you have a diagnosed lower-back condition or this move produces sharp pain rather than muscle fatigue, that's a conversation for a physician or physical therapist, not a modification I'm qualified to design for you.

Double Crunch

I put this move last because it's the one that ties the whole session together — bringing your shoulders and knees toward each other at the same time works the upper and lower ab fibers in one coordinated squeeze, hands cradling your head as pictured, knees pulled tight to a tabletop position.

Supported: keep feet on the floor and lift just your shoulders, pausing before you add the knee tuck.
Standard: knees held at 90 degrees, curling shoulders and knees toward each other on an exhale.
Harder: add a one-second hold at the top of each rep before lowering with control.

Exhale on the effort, every rep — it's a small cue, but it's the difference between abs doing the work and your neck straining to compensate, which is the single most common mistake I see in this movement.

The Takeaway

Pick two or three of these to start with, do them well, and let the rest wait until the first ones feel easy — that's always been a better plan than trying all eight at once and burning out by Thursday.

Your Questions, Answered

Will these moves get rid of lower belly fat specifically?

No, and I want to be straight about that. Spot reduction isn't how bodies work — where you lose fat is determined by genetics and overall activity, not which muscle you're targeting. These moves build real strength in your lower abs, which is worth doing on its own, separate from fat loss.

How often should I do a lower belly fat workout at home?

Two to three times a week with rest days in between is plenty for core work — these muscles recover fast, but they still need recovery. I'd rather see someone do this consistently twice a week for months than burn out doing it daily for two weeks.

I feel these more in my hip flexors than my abs — is that normal?

Very common, especially with reverse crunches and flutter kicks. It usually means the range of motion is a bit too big for where your core strength currently is. Shrink the movement, focus on keeping your low back flat, and the ab engagement tends to show up as strength builds.

Is it safe to do these moves postpartum?

That depends on your individual clearance and recovery, which is genuinely a question for your physician or a pelvic floor physical therapist before you start — not something I can assess from an article. Once you're cleared, the supported versions here are a reasonable starting point.
